Lack of drug effectiveness and increased side effects that can lead to patient nonadherence are some of the biggest challenges providers face related to prescribing medications. The impact and the management of ADRs is complex and in the USA may cost up to 30.1 billion dollars annually.1
Every drug comes with the risk of side effects, and nearly every patient will experience them in some form. The cause of a side effect is often unclear, causing providers difficulty with managing their patient’s drug regimens. Many do not know that these adverse drug events can be due to their patient’s genetics. Such drug-gene interactions can be just as impactful as interactions between two or more medications, so much so that the U.S. Food and Drug Administration has included warning labels on more than 100 medications advising prescribers of their potential drug-gene interaction risk.
